Patent CA-2228068-A1 (CA)
Inventor: OSHIZAWA HIDEKAZU
IPC: G06T11/60
Filed: 1998-01-28
Abstract: Le présent abrégé a trait à une méthode permettant à un système de navigation embarqué à bord d'un véhicule de calculer un itinéraire depuis la position du véhicule jusqu'à une destination voulue. Un utilisateur du système de navigation du véhicule utilise un téléphone cellulaire ou tout autre moyen de communication audio bilatéral sans fil pour contacter un opérateur situé dans un centre de télécommunications distant. L'utilisateur annonce sa destination à l'opérateur. L'opérateur du centre de télécommunications accède à une base de données informatisée afin de déterminer l'emplacement exact de la destination recherchée; il récupère, par exemple, la latitude et la longitude de l'emplacement, l'adresse civique de l'emplacement ou d'autres renseignements similaires. L'opérateur transmet ensuite les informations obtenues au système de navigation embarqué du véhicule grâce à une liaison de données. Le système de navigation embarqué du véhicule reçoit les coordonnées géographiques transmises et les utilise pour calculer l'itinéraire à suivre jusqu'à destination à partir de la position actuelle du véhicule.

Title: Compositions de resine epoxy, preimpregnes, composites solidifies et procedes de fabrication
Inventor: WEIGEL MARK D
IPC: C08G59/18
Filed: 1996-07-29
Abstract: Cette invention concerne des compositions de résine époxy solidifiables, ne contenant de préférence aucun solvant, et dans lesquelles un agent de solidification à base d'amine de fluorène est partiellement dissous par fusion et partiellement dispersé en qualité de solide dans au moins un polyépoxide aromatique. Ces compositions permettent d'obtenir des préimprégnés offrant une bonne adhérence en même temps que des qualités de conservation étonnantes. Cette invention concerne également des composites solidifiés comprenant ces préimprégnés. Les composites solidifiés présentent une faible migration de résine et possèdent des températures de transition du verre qui sont comparables à celles de résines pures solidifiées.

Title: Method for manufacturing a formed piece of metal
Inventor: KAESSI TIMO
IPC: B21J9/02
Filed: 1996-07-01
Abstract: The present invention relates to a method for manufacturing a formed piece of aluminium or some other relatively soft metal. In accordance with the invention, a slice is cut from a rod of aluminium or some other raw-cast metal; the slice forms a blank (3), which is placed on the mould surface (10) of a mould tool (5) rotating about its axis (4), and which is formed using a roll forming tool rotating about its axis (6) inclined to the axis of the mould tool and being in linear rolling contact with the blank surface. The blank is then formed to a substantially disc-shaped piece of plate between the opposite rotating tools (5, 7). The method may be part of the manufacturing process of a frying pan or kettle so that the roll formed piece may comprise the bottom and collar of the utensil, which is bent to form the sides of the cooking utensil at the next pressure turning stage; or, alternatively, the rol formed piece may be fastened as the bottom to a separately manufactured utensil by linear pressing. The formed piece may also be deep-drawn to a globe of a street light, or it may be used as a traffic sign, or as a lid for a softdrink can.

Inventor: ARTAVANISTSAKONAS SPYRIDON
IPC: A61K35/12
Filed: 1996-09-27
Abstract: The present invention is directed to methods for the expansion of non-terminally differentiated cells ("precursor cells") using agonists of Notch function, by inhibiting the differentiation of the cells without inhibiting proliferation (mitotic activity) such that an expanded population of non-terminally differentiated cells is obtained. The cells are preferably stem or progenitor cells. These expanded cells can be used in cell replacement therapy to provide desired cell populations and help in the regeneration of diseased and/or injured tissues. The expanded cell populations can also be made recombinant and used for gene therapy, or can be used to supply functions associated with a particular precursor cell or its progeny cell.

Inventor: BRAUN ELAINE A
IPC: B26D5/02
Filed: 1998-10-29
Abstract: A circular material cutter having a disk-shaped base with a rotating top member attached thereto via a spring and shaft assembly. The top member has a handle formed on its top surface and four legs which extend downwardly from the top surface radial edge, and which have cutting wheels rotatably mounted on their bottom ends of the legs. The shaft and spring assembly extends upwardly from the radial center of the base and is held in a spring receiving portion which extends downward from the radial center of the top member. The shaft and spring assembly allows the top member to be rotated above the base, and also biases the top member away from the base when the device is not in use, to keep the cutting wheels in a retracted position. To use the device, one places the device on sheet material to be cut, pushes down on the top member, and twists it 90~ using the handle, thereby causing the four cutting wheels to cut a circular piece from a sheet of material. An adjustable embodiment permitting selected circles of different radii to be cut is also described.

Abstract: A cable (5) is inserted, by way of a free end (2.1), into a tube (2) wound around a tube reel (1) which is fixed, with its winding axis (y) vertical, onto a carrier (7). The carrier with the tube reel is subjected to a periodical movement having a vertical component and a longitudinal component.  The vertical component is a vertical oscillation having a period (P) and an amplitude (Av = gP2/32) for an, at any rate approximately, "free-fall"  movement during part of each period, preferably during half a period. The longitudinal component is an oscillating rotation around the vertical winding axis of the tube reel having the same period (P) and an amplitude (AL). The "free-fall" movement is preferably commenced when the rotational direction of the oscillating rotation is reversed and becomes backward, as opposed to the insertion direction of the cable. Three embodiments of a device are described.
